Idea for dynamic #QRcode generator

I don’t know if maybe this exist yet. The idea is to have an application that displays an every changing QR code (like the program “watch”). For example this could be:

  • A clock. So the qr code contains the time with seconds
  • location information
  • temperature and other data

21:23

A simpler solution sure is to have an URI which has all the information. But wouldn’t it be nicer to have the information already without internet connection.

Other solution would be to create a bell or a key. So every time somebody scans the code it opens a code that only somebody that stands before the code/door can see. So something knows, that somebody is really standing in front of the door. So you know that you might want to open the door for them, either automatically or you go and open it for them because you get a message from an IM.

The simples form to experiment would be a program that takes any input and displays it immediately. That would not even need to know qr code. But an image viewer might be too slow. If this program already exist, please let me know. I am not a programmer, but would like to see it. 😉
